[osg-users] CxxTest: Custom delta-comparison for osg::Vec3
Hi,
I'm using CxxTest 3.10.1 to unit-test my code. I wrote an extension to
correctly handle osg::Vec3 data, which works fine on MSVC, but won't compile
using GCC 4.3.3.
The extension consists of two parts - a ValueTraits-implementation to print
osg::Vec3 data in readable form, and a delta-function to check if two osg::Vec3
are almost equal.
The extension:
Code:
#include
#include
namespace CxxTest {
CXXTEST_TEMPLATE_INSTANTIATION
class ValueTraits {
std::string s;
public:
ValueTraits(const osg::Vec3& v) {
std::ostringstream oss;
oss << "osg::Vec3(" << v << ")";
s = oss.str();
}
const char* asString() const { return s.c_str(); }
};
template
bool delta (osg::Vec3 x, osg::Vec3 y, D d) {
return ((y.x() >= x.x() - d) && y.x() <= x.x() + d) &&
(y.y() >= x.y() - d) && y.y() <= x.y() + d) &&
(y.z() >= x.z() - d) && y.z() <= x.z() + d));
}
}
I use it in a test like this:
Code:
void test_vec3 {
osg::Vec3 a(1.0, 1.0, 1.0);
osg::Vec3 b(1.01, 1.01, 1.01);
TS_ASSERT_DELTA(a, b, 0.001); // Fails
TS_ASSERT_DELTA(a, b, 0.1); // Passes
}
When compiling with gcc it seems like my delta-function is not found or used,
the compiler tries to use the generic templated "delta(X x, Y y, D d)", which
tries to test for "y >= x - d && y <= x + d".
Compiler-output:
Code:
/home/docdrum/dev/OsgProjectTests/tests/cpptests/lib/cxxtest/cxxtest/TestSuite.h:
In function »bool CxxTest::delta(X, Y, D) [with X = osg::Vec3f, Y =

Fehler 1
make[1]: *** [tests/cpptests/unit/CMakeFiles/UnitTest.dir/all] Fehler 2

I tried using all combinations of osg::Vec3f instead of osg::Vec3, using
const-references, float- and double-parameters for d instead of templating...
Any ideas how I can make this work on GCC?
Thank you!
Cheers,
Colin

[osg-users] Forward declared classes and ref_ptrs
Hi all, to reduce compile time dependencies, I prefer using forward delcarations instead of #includes, where possible. This doesn't seem to work with osg::ref_ptr<>, which needs complete type informations. Is there a workaround to use ref_ptrs and as few include-files as possible?

Re: [osg-users] [RFC] osgViewer: solution for omitted key release events
Hi Folks, Have you considered some kind of layered approach? Maybe an immediate interface to the physical keycodes, sending events for every _key_ press and release. Another layer could then use the windowing-system mappings to convert these events to _character_ press/release events. If this second layer would be added per default it should not break current applications. Clients that need the physical codes could easily disable the translation layer, or even replace it with their own keyevent-translation scheme.

Re: [osg-users] missing includes
Hi all, The gcc-team weeded out some includes in their headers for the 4.3 release. If a program uses a cstdlib function, but does not include the header file because it was already pulled in by another c++ header, it will break now. I don't know which gcc version Jaunty defaults to, but if it is a 4.3 release, this would be the problem.

Still I've been compiling a couple of osg based application : VTP, osgEphemeris, osgearth. The fact is that for most of them I had to add a couple of #include directive to make them compile. It's always some c++ wrapping of c headers like or . I don't understand if it is possible that those application compile without problem on some computer. Which would mean that I have to tune some environment variables or whatever. Is this the case or should I report those missing directive to the concerned developper? Thanks for any answer on this. -- Loïc Simon ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >>> >>> >>> ___ >>> osg-users mailing list >>> osg-users@lists.openscenegraph.org >>> http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >>> >> >> >> >> -- >> Loïc Simon >> >> ___ >> osg-users mailing list >> osg-users@lists.openscenegraph.org >> http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >> > > > ___ > osg-users mailing list > osg-users@lists.openscenegraph.org > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > > ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
